POWDER DISPENSER.

Application filed July 11, 1924, Serial No. 725,489. Renewed September29, 1925.

This invention relates to receptacles in general and it pertains moreparticularly to the species used for the distribution of powder.

One object of the invention is to produce a nonrefillable article. ofthe kind described,

adapted to be removably inserted into an low priced materials, so as topermit the same to be discarded, when emptied of its contents.

Still another object consists in. producing an article of the class setforth,wherein means embodied in a relatively unyielding internal rim orledge render the later -sufliciently resilient and pliable to conform,to the coacting surface of a closure member, and make a tight jointtherewith, dispensing as well with seats of soft texture intermediatethe before named ledge and member.

A still further object resides in providing an article of the typereferred to, comprising but few plain parts, exclusively of metal;

readily produced,"--'char ed and assembled bythe least expensive la or;besides reliable and convenient in operation.

Other objects and advantages of the invention will become apparent asthe specification proceeds.

With the aforesaid objectsin view, the inventon consists of the novelcombinations and arrangements of parts hereinafter described in theirpreferred embodiments, pointed out in the s'ubjoined claims, andillustrated on the annexed drawing, wherein like parts are designated bythe same reference characters throughout the several views.

Generally described, the article forming the subject of the presentinvention, consists of a pair of comparatively shallow andlow rimmedsaucer-like elements, fittin in converted and inverted relation oneinside of the other so as to constitute a powder box or receptacle. Thelower element is formed, around its peripheral bottom corners, with 'thethereto pertaining arrows;

an inwardly turned annular rabbet into which is crimped the free,depending edge of the rim of the upper element, in order to preventthese elements from being disassociated. The to of the upper element isprovided with a attened and depressed portion having a central openingthrough which the powder is discharged. A gradually dished.

field reaches intermediate the circumferences of the depressed portionand the rim of the top element. At a specified distance from the inneredge of the discharge opening are formed in the depressed portion, aseries of arcuate incisions or closed slits which serve to weaken theaforesaid edge and make it pliable or flexible. Coacting with theunderside of the before mentioned edge of the discharge opening, is aclosure member which is held up against the latter by means of a springhavin differential resiliency.

-Means are provide to limit the amount that the closure member may bedepressed to admit of a certain outflow of powder from the receptacle,and also to make it more difficult or inconvenient to refill through thedischarge opening. The power of the spring is sufficient to urge thereceptacle elements apart andthus render them, as well as the closuremember, inoperative, if an attempt be made to pry open the crimped jointintermediate the said elements.

" The advantages of the invention as here outlined are best realizedwhen all of its features 'and instrumentalities are combined in the oneand same structure, but, useful devices may be produced embodying lessthan the whole.

It will be obvious to those skilled in the art to which the inventionappertains, upon becoming conversant with the details thereof, that thesame may be incorporated in several different constructions. Theaccompanying drawing, therefore, is submitted merely as showing thepreferred exemplification of the invention.

In the said drawing Figure I- is a full top plan view of this improvedpowder distributor;

Fig. II is a section on the line IIII of Fig. I, looking upwardly in thedirection of Fig. III is also a top plan view of the article inquestion, from which some parts are omitted; and

' rim is of a size to take over the low rim with a tight fit, on theorder of a cover.

Below its marginal annulus the said upper shell 17, is provlded in themiddle thereof, with an approximately flat, depressed portion 23, thecentre of which has cut therein an opening 25. Intermediate the innerand outer circumferences of the annulus 19 and the said depressedportion, respectively, extends a. sloping or funnel-shaped field 27. Forthe purpose of making theborder of the opening 25 yielding or flexible,so that 1t will accommodate itself tightly to the upper face of aclosure "member 29, the said portion is weakened transversely. This isconveniently accomplished by embodying on the flat border or ledge 23, aseries of incisions or indentations 31, in proximity to the said opening25. By preference, these incisions may consist of a plurality of arcuateslits, spaced apart both endwise and laterally, being as shown disposedin staggered arrangement with relation to one another. The slits areindicated by single lines in Fig. I, but in the enlarged disclosureaiforded by Fig. IV, which is taken across two of the aforesaid slitsor'incisions, it clearly appears that the metal between them, is forceddownwardly or ofi'set relatively to the plane it was originally situatedin, still without severing the same from the ledge. Subsequently topressing the bridges or connecting strips 33 intermediate the beforementioned slits back into the normally flat position, as indicated inFig. II, the opening 25is punched out, so as not to wrinkle or distortthe interior edge thereof. While the treatment thus given to the flatedge or border 23, renders the same quite pliable, it does not permitany of the powder to leak through the incisions, in view of the factthat their adjacent sides are ultimately in close contact with oneanother.

The hereinbefore named closure 29, is preferably composed of a slightlycrowned or convex disc like plate surrounded by a downwardly curvedperipheral border or edge 35. The edge last referred to, is held inabutting relation to the underside of the upper shells flexible innermargin 23, by the outer ends of shorter and stifl'er tongues 37radiating from the central part of an astralis depressed in order todischarge from the box or receptacle some of the powder containedtherein, out through the opening 25 in the upper shell 17, fordistribution over the ledge 23 and the sloping field 27 where it can bemopped up by a. powder-puff (not shown), the longer tongues 41 which arethe lowermost as well, flex first, until an ear 43 touches the inside ofthe bottom 13. If the downward pressure is continued, the higher locatedtongues 37 will also bend till the underside of the closure 29 strikesagainst another ear 45. Both of these ears, as seen to best advantage inFig. III, are stamped out of the central part of the said spring 39, andbent therefrom in opposite directions. The said ears 43 and 45constitute stops for limiting the opening movement of the closure memberrelatively to the inner marginal ledge 23. The construction of thespring 39 is such that it not only holds up the closure, but guides thelatter as well.

The means for preventing the container and cover elements 11 and 17respectively, from bein disassociated, comprise as indicated at t elower part of Fig. II and also in Fig. III, a rabbet 47 of a certainwidth, formed with the peripheral corners of the bottom 13 and the rim15, which rabbet as shown, is turned inwardly of the shell 11. The freeor depending edge of the rim 21 pertaining to the cover shell 17 is,subsequently tothe last named cover having been placed over itscompanion shell 11, crimped as represented at 49, into the said rabbet47 from the underside. The interstice intervening between the innercircumferences of the rabbet and the crimped edge 49, may, asrepresented at 51, be filled with a suitable sealing material, in orderto divulge to the purchaser of the article if the same has been tamperedwith.

The spring 39 possesses ample strength to urge the shells 11 and 17 awayone from the other, prior to the edge 49 being crimped over the cornerof the rabbet 47, so that if an attempt is made to turn over outwardlythe said edge, for the purpose of recharging the bottom shell, the rims15 and 21, of the latter and the cover shell, respectively, cannotremain in tight association. Nor will, under the conditions mentioned,the closure 29 engage the ledge 23 with sufficient pressure to precludeleakage of powder therebetwecn, and therefore the article is practicallyinoperative unless the shells 11 and 17 are intersealed. The averageuser of an article of this kind, does not possess appropriate implementsfor neatly taking apart and putting together the ele- I ments spoken of.Even a fairly good meient.

chanic could only do this a few times before the edge 49 would crumbleaway under repeated bendings. Attempts to re-fill the assembledreceptacle through its discharge opening, would be too tedious andinconven- Truly the space between the border 35 of the depressed closureand the overlying inner margin 23, is large enough to afford an outflowof powder when the box lodged within a surrounding vanity case, isshaken or agitated. But this space is entirely too constricted to permitentering the powder therethrough, counterwise to the air passing out ofthe receptacle which it has to replace. Matters would only be Q madeworse by trying to tap or knock the tity of powder therein, brings upbox with the fingers or against some hard object, with a charge ofpowder deposited on top of the closure, as this could only serve to stirup and cause the powder to fly about.

From the foregoing, it will be obvious that a practicallynon-refillable, inexpensive container has been devised, out of which therequired amount of powder can be dispensed at will. The mere act ofpressing down upon the closure thereof with a superposed powder-pufl',while giving the container and its encompassing casing, more or less ofan accentuated shake, depending upon the quanenough of the latter for afacial applicatlon. Whenever the inter-sealed container shells areemptied of their contents, they are discarded and a set of new and fullones is substituted in their stead. When the article is to be filledfrom the beginning, the powder is poured into the lower shell 11 whereinthe spring 39 has previously been inserted. Subsequently, the closure 29is laid upon the upper tongues 37 of the spring, after which the covershell 11 is placed over the foregoing assemblage, and finally sealed toprevent disassociation as hereinbefore described.

hile a certain preferred embodiment of this device has been shown anddescribed, it will be understood that changes in the form, arrangements,proportions, sizes and details thereof may be made, without departingfrom the scope of the invention as defined by the appended claims.
